Interestingly, almost all contemporary coding style suggestions for
modern languages I could find specify visually segregating function
calls from variables by using MixedCasePascalStyle for one and
lower_case_underscore for the other. I've rarely seen an advocate of
both styles throughout. That said, I think the overuse of
capitalization is a grievance not to be taken lightly, one which most
net users have learned, often by harsh rebuke, is TANTAMOUNT TO
SHOUTING. Purveyors of this false truth can usually be excused as
having been damaged early on by over-exposure to FORTRAN (ditto for
GOTO). None of the coding style guidelines I've found recommend
significant use of ALL-CAPS.
I weigh in on the side of the quieter, less visually obstreperous use
of lower case variables and identifiers, saving upper case for spare
and special purposes like certain comparisons (AND, OR, EQ, NOT) and
keywords (device,/COLOR), which might otherwise get lost in the line
noise. I like MixedCase (but not uppercase) Methods, and lower-case
for most functions (except those associated with methods, or OO-like
bundles of code). And I use syntax coloring, which both IDLDE and
IDLWAVE do with aplomb, to provide additional visual differentiation.
Just the opinion of one,
JD
